Description

Technical Field

[0001] This invention belongs to the field of personal hygiene devices, and particularly relates to an oral care device. Background Technology

[0002] Dental calculus, also known as dental plaque, is typically found on the tooth surface near the openings of salivary glands. This includes the lingual surfaces of the lower anterior teeth, the buccal surfaces and necks of the upper posterior teeth, and other tooth surfaces that are not easily reached by the oral mucosa. Initially, dental calculus is a soft, milky-white deposit that hardens gradually through calcification. It is composed of 75% calcium phosphate, 15%–25% water, organic matter, manganese phosphate, calcium carbonate, and trace amounts of potassium, sodium, and iron, and can appear yellow, brown, or black.

[0003] If your teeth have tartar buildup on the surface or roots, or if they are yellowed or blackened, you need to have them professionally cleaned regularly at the dentist. However, this is generally expensive, and appointments with dentists require advance booking, which can be inconvenient. If you use a regular dental cleaning device, you can probably clean the front teeth, which are more easily visible, but it won't be able to clearly see and clean the teeth closer to the back of your mouth. Also, you might accidentally damage the tooth surface or gums during the cleaning process.

[0004] In existing technologies, when cleaning the inner wall of teeth (the side of the teeth facing into the mouth), users usually visually identify which teeth have stains before cleaning them. However, the above-mentioned teeth cleaning methods do not test the teeth; they only know that the teeth have stains but do not detect and present any problems with the teeth. Therefore, existing oral care devices cannot provide users with the function of detecting dental symptoms, resulting in a poor user experience. Summary of the Invention

[0005] The purpose of this invention is to provide an oral care device and scanning system, which aims to solve the technical problem that existing technologies cannot provide users with the ability to detect dental symptoms.

[0006] This invention is implemented as follows:

[0007] An oral care device includes a handheld housing and a working tip. The handheld housing includes a working head with an inner cavity and a handheld component connected to the working head and having an inner cavity. The working tip is located at the end of the working head. The device is characterized in that: a dental endoscope assembly for detecting and acquiring dental information is provided within the inner cavity of the working head near the working tip. The dental endoscope assembly includes a dental endoscope mainboard disposed on the working head, a light source system disposed on the dental endoscope mainboard for detecting the state of the teeth, and a camera mechanism inserted into the dental endoscope mainboard for acquiring dental information. The light source system has at least one optical axis, which is parallel to the optical axis of the camera mechanism.

[0008] Furthermore, the light source system includes a pure white lamp that emits pure white light and / or a blue lamp that emits blue light and / or a pure white lamp that emits pure white light with a bluish tint.

[0009] Furthermore, the light source system includes a first lamp group and a second lamp group respectively disposed on both sides of the camera mechanism and electrically connected to the dental endoscope main board, wherein the first lamp group and the second lamp group are arranged opposite to each other.

[0010] Furthermore, the camera mechanism includes a camera fixing tube passing through the dental endoscope main board, an endoscope disposed inside the camera fixing tube, and a flexible circuit board electrically connected to the endoscope. The flexible circuit board is electrically connected to the dental endoscope main board, and the optical axis of the camera mechanism is the optical axis of the endoscope.

[0011] The dental endoscope mainboard is equipped with multiple supplementary lighting devices, which are arranged at intervals around the optical axis of the endoscope.

[0012] Furthermore, the dental endoscope assembly also includes a dental endoscope lens disposed on the end face of the working head facing the working tip. The dental endoscope lens is provided with a first nano-coating area and a second nano-coating area, wherein the first nano-coating area is disposed in the area of ​​the dental endoscope lens corresponding to the first lamp group, and the second nano-coating area is disposed in the area of ​​the dental endoscope lens corresponding to the second lamp group.

[0013] Furthermore, the area on the dental endoscope lens corresponding to the supplementary lighting device is a transparent area through which light emitted from the supplementary lighting device can pass.

[0014] Furthermore, a main control module is provided inside the cavity of the handheld component; the main control module includes a Wi-Fi motherboard, an ultrasonic motherboard electrically connected to the Wi-Fi motherboard, and a battery electrically connected to the ultrasonic motherboard, and a gyroscope is electrically connected to the Wi-Fi motherboard.

[0015] Furthermore, the supplementary lighting device is an optical fiber or a supplementary light.

[0016] Furthermore, the oral care device also includes an ultrasonic component, which includes an ultrasonic transducer disposed within the inner cavity of the handheld component and near one end of the working head, an ultrasonic ceramic plate connected to the working shaft of the ultrasonic transducer, and an amplitude transformer connected to the working shaft of the ultrasonic transducer.

[0017] The amplitude rod extends through the end of the working head and connects to the working tip.

[0018] Furthermore, the high-frequency ultrasonic frequency of the ultrasonic transducer is between 26kHz and 40kHz, and the low-frequency ultrasonic frequency of the ultrasonic transducer is between 200Hz and 400Hz.

[0019] Furthermore, the handheld housing is provided with a water spray channel, which passes through the ultrasonic transducer and the amplitude transformer in sequence. The working tip has a working inner cavity that communicates with the water spray channel, and the working tip has at least one water outlet that communicates with the working inner cavity.

[0020] Furthermore, the oral care device also includes a base, in which a charging component is provided, and the working head is inserted into the base and electrically connected to the charging component.

[0021] The beneficial effects of this invention are as follows: A light source system mounted on the mainboard of a dental endoscope is used to detect teeth in the oral cavity. Different colors of light emitted by the light source system detect tartar, plaque, and cavities on the teeth. The user can then display the detection results on a display terminal using an oral care device, allowing the device to target specific areas for cleaning. A camera captures tooth information, transmitting real-time images of the teeth requiring cleaning to the display terminal via a communication connection between the oral care device and the display terminal. This facilitates real-time observation of the teeth's current and cleaned state during cleaning. Furthermore, by aligning the optical axis of the light source system parallel to the optical axis of the camera, the light source system and the camera are aligned in their shooting directions, ensuring the light-emitting area of ​​the light source system is within the image acquisition area of ​​the camera. This allows the camera to capture real-time images of the detected teeth. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0042] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0043] It should also be noted that the directional terms such as left, right, up, and down in this embodiment are only relative concepts or are based on the normal use of the product, and should not be considered as restrictive.

[0044] like Figures 1 to 4As shown, an oral care device 100 includes an upper outer shell 10 and a lower outer shell 11 that is snapped and fixed to the upper outer shell 10. A waterproof rubber ring 12 is fitted at the connection between the upper outer shell 10 and the lower outer shell 11. When the upper outer shell 10 and the lower outer shell 11 are spliced ​​together, the waterproof rubber ring 12 is compressed after splicing, causing the waterproof rubber ring 12 to undergo elastic deformation, thereby achieving a seal at the connection between the upper outer shell 10 and the lower outer shell 11, thus increasing the waterproof performance of the oral care device 100. Through the sealed connection of the above-mentioned waterproof method, the upper outer shell 10 and the lower outer shell 11 are spliced ​​together to form a sealed receiving cavity, thereby making the receiving cavity of the oral care device 100 waterproof, and thus making the electronic components placed in the oral care device 100 waterproof.

[0045] The assembled upper shell 10 and lower shell 11 have a handhold part 13 with an inner cavity and a working head 14 with an inner cavity. The working head 14 has a working tip 2 at one end away from the handhold part 13. The handhold part 13 is the part that the user holds when operating. The working head 14 extends from the end where the working tip 2 is installed to the end connected to the handhold part 13.

[0046] like Figure 3 and Figure 4 As shown, a main control module 3 is installed inside the handheld unit 13. The main control module 3 includes a Wi-Fi motherboard 31 and an ultrasonic motherboard 32 electrically connected to the Wi-Fi motherboard 31. Both the Wi-Fi motherboard 31 and the ultrasonic motherboard 32 are coated with a nano-waterproof layer. This nano-waterproof layer is a transparent thin-film nano-coating with a thickness of 50-800 nanometers, approximately one-thousandth the diameter of a human hair. The low-convex surface of the nano-waterproof layer can adsorb surrounding gas molecules, forming a stable thin-film cushion, preventing direct contact between the surfaces of the Wi-Fi motherboard 31, the ultrasonic motherboard 32, and the electronic components attached to them, and water molecules. The formation of an extremely fine mesh film on the surfaces of the Wi-Fi motherboard 31 and the ultrasonic motherboard 32 effectively reduces the surface energy of these surfaces and the electronic components, causing the contact angle of water droplets deposited on the surfaces of the Wi-Fi motherboard 31 and the ultrasonic motherboard 32 to approach its maximum value. Therefore, the surfaces of the Wi-Fi motherboard 31 and the ultrasonic motherboard 32 exhibit strong superhydrophobic properties.

[0047] The ultrasonic mainboard 32 is located at the end of the handheld part 13 away from the working head 14. The ultrasonic mainboard 32 is equipped with a battery 33 that powers the oral care device 100. The battery 33 is a flexible battery. The ultrasonic mainboard 32 integrates an anti-interference module, which effectively reduces the impact of external communication signals on the wireless transmission of the oral care device 100 and reduces the mutual interference of internal components of the oral care device 100 to a certain extent.

[0048] The ultrasonic mainboard 32 and the WiFi mainboard 31 are connected by a ribbon cable (not marked in the figure), and each of the WiFi mainboard 31 and the ultrasonic mainboard 32 is provided with a connector for the ribbon cable to be plugged in (not marked in the figure), and the WiFi mainboard 31 is located on one end of the handheld part 13 away from the ultrasonic mainboard 32.

[0049] like Figure 3 and Figure 4 As shown, a shock-absorbing silicone pad 34 is provided between the side of the Wi-Fi motherboard facing the lower housing 11 and the lower housing 11. The side of the shock-absorbing silicone pad 34 facing the Wi-Fi motherboard 31 has holes and slots for adapting to the electronic components on the Wi-Fi motherboard 31, so as to facilitate the assembly of the Wi-Fi motherboard 31, effectively reduce the size of the oral care device 100, and also reduce the occurrence of screen shaking caused by external factors in the wireless transmission of the Wi-Fi motherboard 31. The shock-absorbing silicone pad 34 is installed in the area where the shock-absorbing silicone pad 34 is projected onto the lower housing, and the shock-absorbing silicone pad 34 is adapted to the lower housing 11.

[0050] A shock-absorbing foam 4 is provided between the battery 33 and the WiFi motherboard 31, which makes the assembly between the battery 33 and the WiFi motherboard 31 more compact, thereby improving the shock resistance of the WiFi motherboard 31 and the battery 33 and reducing the impact of external vibration on the WiFi motherboard 31; the WiFi motherboard 31 is connected to a WiFi antenna (not shown in the figure) when powered on, so as to transmit data with the display terminal through the WiFi antenna.

[0051] The Wi-Fi motherboard 31 also integrates a gyroscope (not shown in the figure). The Wi-Fi motherboard 31 emits a Wi-Fi signal to connect to an external display terminal. After the oral care device 100 is connected to the display terminal, the oral care device 100 can transmit the captured image to the display terminal. The gyroscope measures the rotation and deflection movements accordingly and can accurately analyze and judge the user's actual movements. Based on the movements, the gyroscope can perform corresponding operations on the display terminal. The gyroscope detects the shaking and rotation angle of the oral care device 100 and then calculates the distance or angle that the oral care device needs to compensate for, so that the image displayed on the display terminal by the lens maintains the original direction and angle. This allows the user to perform precise fixed-point operations when using the oral care device 100 with the gyroscope, increasing the user's comfort.

[0052] like Figure 3 and Figure 4As shown, an ultrasonic component 5 connected to the working tip 2 is provided inside the working head 14; the ultrasonic component 5 includes an ultrasonic transducer 51, an ultrasonic ceramic plate 52 and an amplitude transformer 53 connected in sequence. The high-frequency ultrasonic frequency of the ultrasonic transducer 51 is between 26kHz and 40kHz, and the low-frequency ultrasonic frequency emitted is between 200Hz and 400Hz. The low-frequency ultrasonic waves can be used for cleaning teeth, similar to brushing teeth.

[0053] The anti-vibration silicone pad 34 extends away from the ultrasonic motherboard 32 towards the ultrasonic transducer 51 and houses the ultrasonic transducer 51 on the anti-vibration silicone pad 34 to achieve the purpose of shock absorption for the ultrasonic transducer 51; the ultrasonic ceramic plate 52 is provided with a data line electrically connected to the ultrasonic motherboard 32, and a shielding tube 54 is sleeved on the data line to reduce the impact of external communication signals and internal electronic component communication signals on Wi-Fi transmission information.

[0054] The amplitude transformer 53 connected to the ultrasonic transducer 51 is in a bent state, wherein the end of the amplitude transformer 53 away from the ultrasonic ceramic plate 52 is bent, and the bending angle of the amplitude transformer 53 is between 110 degrees and 170 degrees, preferably 120 degrees; wherein the diameter of the amplitude transformer 53 is 3mm.

[0055] The aforementioned amplitude transformer 53 is located inside the working head 14, and the end of the amplitude transformer 53 away from the ultrasonic ceramic plate 52 extends out of the end of the working head 14 away from the handheld part 13. The end face of the amplitude transformer 53 extending out of the working head 14 is flush with the end face of the working head 14. The end of the working head 14 near the working tip 2 is bent, and the bending angle is the same as the bending angle of the amplitude transformer 53. Furthermore, the extension direction and bending amplitude of the working head 14 from the connection point between the working head 14 and the handheld part 13 to the end of the working head 14 near the working tip 2 are the same as the extension direction and bending amplitude of the amplitude transformer 53, so as to achieve synchronous bending of the working head 14 and the amplitude transformer 53, so that the user can more easily clean the stains on the inner wall of the teeth.

[0056] Specifically, a retaining ring 55 is provided on the end of the amplitude transformer 53 near the ultrasonic ceramic plate 52, and the retaining ring 55 is snapped onto the lower housing 11 to limit the position of the ultrasonic component 5 by limiting the position of the amplitude transformer 53, which is conducive to the transmission of the mechanical vibration energy converted by the ultrasonic transducer 51. A shockproof silicone sleeve 56 is fitted on the end of the amplitude transformer 53 that protrudes from the working head 14, and the shockproof silicone sleeve 56 passes through the end of the working head 14. The end of the amplitude transformer 53 that protrudes from the working head 14 is fixed to the working head 14 by an interference fit assembly. This not only helps the oral care device 100 to be waterproof during operation, but also effectively reduces the occurrence of damage to the amplitude transformer 53 caused by external factors due to vibration of the oral care device 100. The working tip 2 is detachably connected to the end of the amplitude transformer 53 that protrudes from the working head 14 by a screw connection, so that the amplitude transformer 53 can better transmit the mechanical vibration converted by the ultrasonic transducer 51 to the working tip 2.

[0057] like Figure 2 and Figure 3 As shown, the working head 14 includes a bending portion 141 and a connecting portion 142 integrally formed with the bending portion 141. The end of the connecting portion 142 away from the bending portion 141 is connected to the hand-held portion 13. The extension direction from the connecting portion 142 toward the bending portion 141 is consistent with the extension direction of the amplitude rod 53, so that the bending angle and bending direction of the working head 14 are consistent with the bending angle and bending direction of the amplitude rod 53.

[0058] like Figures 3 to 5 As shown, the working head 14 is also equipped with a camera mechanism 62 arranged parallel to the amplitude transformer 53; the camera mechanism 62 includes a camera fixing tube 621, an endoscope 622, and a flexible circuit board 623; the camera fixing tube 621 is disposed in the bent portion 141, and the camera fixing tube 621 passes through the end face of the working head 14 near the working tip 2, wherein the end face of the end of the camera fixing tube 621 passing through the working head 14 is flush with the end face of the end face of the amplitude transformer 53 passing through the working head 14, and the camera fixing tube 621 is coaxially arranged with the endoscope 622, and the camera fixing tube 621 is sleeved on the endoscope 622, so that... The endoscope 622, which is mounted inside the camera mounting tube 621, is parallel to the working tip 2 mounted on the amplitude transformer 53. This makes the shooting direction of the endoscope 622 parallel to the working direction of the working tip 2, and thus the working area of ​​the working tip 2 mounted on the bent amplitude transformer 53 is within the shooting range of the endoscope 622. This allows the endoscope 622 to collect the working condition of the working tip 2 in real time while the working tip 2 is working, so that when the user uses the oral care device 100, they do not need to open their mouth too wide to provide a large working space for the oral care device 100, and the working condition of the working tip 2 can be fully presented.

[0059] One end of the flexible circuit board 623 is connected to the endoscope 622, and the other end passes through the connector 142 and is connected to the wifi motherboard 31. A nano waterproof layer is also attached to the flexible circuit board 623.

[0060] The endoscope 622 and the camera fixing tube 621 are coaxially arranged so that after the camera fixing tube 621 is fixed, the shooting direction of the endoscope 622 is consistent with the working direction of the working tip 2. The endoscope 622 is equipped with a wide-angle lens to effectively expand the shooting range of the endoscope 622 and improve the clarity of the working area of ​​the working tip 2 captured by the endoscope 622. This allows the user to have more precise control over the teeth cleaning process, thereby improving the safety of the teeth cleaning process. The power of the wide-angle lens is between 85 degrees and 125 degrees, and the depth of field of the wide-angle lens reaches 5-100mm, allowing the entire oral cavity and teeth to be clearly seen from a long distance.

[0061] In addition, the lens of the endoscope 622 is coated with a dustproof and anti-fog coating. When the endoscope 622 is inserted into the oral cavity, liquid is present in the working environment. Therefore, the coating treatment on the lens of the endoscope 622 effectively reduces the adhesion of liquid to the endoscope 622, thereby reducing the possibility of unclear real-time images displayed on the display terminal due to liquid adhesion. At the same time, the lens of the endoscope 622 has a dustproof function. On the one hand, it minimizes the possibility of human infection caused by dust on the endoscope 622. On the other hand, it improves the clarity of the real-time images captured by the endoscope 622.

[0062] like Figures 3 to 6 As shown, a dental endoscope assembly 6 is provided on the end face of the working head 14 facing the working tip 2. The dental endoscope assembly 6 includes a dental endoscope main board 61 electrically connected to the flexible circuit board 623, the aforementioned camera mechanism 62 passing through the dental endoscope main board 61, and a light source system (not marked in the figure) provided on the dental endoscope main board 61.

[0063] like Figure 6 As shown, the dental endoscope mainboard 61 has a camera mounting hole 611 for the camera mechanism 62 to pass through and a mounting hole 612 arranged parallel to the camera mounting hole 611 for the amplitude transformer 53 to pass through. The light source system includes a first lamp group 631 electrically connected to the dental endoscope mainboard 61 and a second lamp group 632 arranged opposite to the first lamp group 631, and the camera mounting hole 611 and the mounting hole 612 are located between the first lamp group 631 and the second lamp group 632.

[0064] The first light group 631 includes a first pure white light 6311, a first blue light 6312, a first pure white light with a bluish tint 6313, a second blue light 6314, and a second pure white light 6315 arranged side by side in sequence from the mounting hole 612 toward the camera mounting hole 611; the second light group 632 includes a first pure white light with a bluish tint 6313, a second blue light 6314, a third pure white light 6323, a fourth blue light 6324, and a third pure white light with a bluish tint 6325 arranged side by side in sequence from the mounting hole 612 toward the camera mounting hole 611.

[0065] Among them, the first positive white lamp 6311, the second positive white lamp 6315 and the third positive white lamp 6323 are all positive white lamps, and the optical axes of all the positive white lamps are set parallel to the optical axis of the camera mechanism, so that the illumination coverage area of ​​the positive white lamps is located within the image acquisition area of ​​the camera mechanism. Different spectral coatings with different values ​​are attached to the light-emitting end of the positive white lamps to cooperate with the light of the positive white lamps, so that the camera mechanism can capture the state of the teeth detected by the positive white lamps in real time, so that the state of the teeth can be clearly observed when the oral care device 100 is inserted into the oral cavity.

[0066] The first blue lamp 6312, the second blue lamp 6314, the third blue lamp 6322, and the fourth blue lamp 6324 are all blue lamps, and the optical axes of all the blue lamps are arranged parallel to the optical axis of the camera mechanism so that the illumination coverage area of ​​the blue lamps is located within the image acquisition area of ​​the camera mechanism. Different spectral coatings of varying values ​​are attached to the light-emitting ends of the blue lamps to work in conjunction with the light, enabling the camera mechanism to capture real-time images of the teeth being inspected by the blue lamps. Furthermore, by applying contrast agents or tablets (contrast agents) to the teeth to reveal plaques, under blue light irradiation, areas of tartar, plaque, and cavities on the teeth can be clearly observed with the naked eye without the need for filter glasses. The inclusion of a blue light wick in the dental endoscope assembly 6 also enables the detection of tartar, plaque, and cavities.

[0067] The first bluish-white lamp 6313, the second bluish-white lamp 6321, and the third bluish-white lamp 6325 are all bluish-white lamps, and the optical axes of all the lamps are arranged parallel to the optical axis of the camera mechanism. This ensures that the illumination coverage area of ​​the lamps is within the image acquisition area of ​​the camera mechanism. Different spectral coatings of varying values ​​are attached to the light-emitting ends of the lamps to work in conjunction with the light emitted, enabling the camera mechanism to capture real-time images of the teeth being examined by the lamps. Furthermore, by applying a contrast agent or tablet (contrast agent) to the teeth, areas with plaque can be clearly observed with the naked eye under the illumination of the bluish-white lamps, even without the need for filter glasses.

[0068] Among them, there are four supplementary lights 624 arranged in a ring around the camera mounting hole 611, and the four supplementary lights 624 are evenly distributed around the camera mounting hole 611.

[0069] like Figures 3 to 6 As shown, when the upper outer shell 10 and the lower outer shell 11 are closed, the dental endoscope main board 61 is snapped into the working head 14 and located at the end of the working head 14 where the working tip 2 is mounted. A dental endoscope lens 64 is provided on the side of the dental endoscope main board 61 facing the working tip 2 to close the end of the working head 14 facing the working tip 2. A first nano-coating area 641 is provided on the dental endoscope lens 64 corresponding to the area of ​​the first lamp group 631. When the lamp on the first lamp group 631 illuminates the first nano-coating area 641, the first nano-coating area 641 receives light, fills the first nano-coating area 641, and illuminates the oral cavity area to be examined. The dental endoscope lens 64... A second nano-coating area 642 is provided in the area of ​​the second lamp group 632. When the lamp on the second lamp group 632 shines on the second nano-coating area 642, the second nano-coating area 642 will receive light and cover the second nano-coating area 642 and irradiate the human oral cavity area to be tested. A transparent area 643 is provided on the dental endoscope lens 64 corresponding to the area of ​​the four supplementary lights 624, so that the illumination light emitted by the supplementary lights 624 can pass through the transparent area 643 and be emitted out of the working head 14. There are four transparent areas 643, which correspond to the positions of the four supplementary lights 624, so that the light emitted by each supplementary light 624 is uniform and complete.

[0070] The dental endoscope lens 64 has an endoscope mounting hole (not marked in the figure) for the endoscope 622 to pass through at the position corresponding to the endoscope 622, and the dental endoscope lens 64 has an amplitude rod mounting hole (not marked in the figure) for the amplitude rod 53 to pass through at the end of the dental endoscope main board 61.

[0071] The other areas of the dental endoscope lens 64 (i.e., the areas of the dental endoscope lens 64 other than the first nano-coating area 641, the second nano-coating area 642, and the transparent area 643) are coated with a black coating, which can effectively absorb the light irradiated by the first lamp group 631, the second lamp group 632, and the detection group to areas other than their corresponding areas, thereby reducing the likelihood of scattering light from the light source on the dental endoscope assembly 6. In addition, the black coating also helps to cover the dental endoscope mainboard 61, thus adding to the aesthetics of the oral care device 100.

[0072] like Figure 5 and Figure 6As shown, a dental endoscope circuit board 645 is provided between the dental endoscope main board 61 and the flexible circuit board 623. The dental endoscope main board 61 and the flexible circuit board 623 of the camera mechanism 62 are connected through the dental endoscope circuit board 645. A shielding layer (shielding paint) for shielding signals is attached to the dental endoscope circuit board 645 to reduce signal interference between the dental endoscope circuit board 645 and the components in the camera mechanism 62, thereby improving the stability of signal transmission of the oral care device 100.

[0073] The end of the dental endoscope mainboard 61 furthest from the camera mounting hole 611 is electrically connected to a contact terminal 613 for contact charging, which extends through the upper housing 10 and the lower housing 11, so that the oral care device 100 can be charged with a charging device. Additionally, the camera mounting tube 621 in the camera mechanism 62 passes through the camera mounting hole 611, so that one end of the camera mounting tube 621, which is assembled between the upper housing 10 and the lower housing 11, passes through the camera mounting hole 611, thereby improving the stability of the endoscope 6 within the oral care device 100 and thus enhancing the stability of the endoscope 6 within the camera mounting tube 621. The stability of 22 is improved, thereby enhancing the stability of the endoscope 622 when acquiring images; the above-mentioned anti-vibration silicone sleeve 56 is inserted into the mounting hole 612 of the dental endoscope main board 61, and the end of the amplitude rod 53 protruding from the working head 14 is inserted into the anti-vibration silicone sleeve 56, so that one end of the amplitude rod 53 protruding from the working head 14 is fixed in the anti-vibration silicone sleeve 56, thereby improving the stability of the end of the amplitude rod 53 near the working tip 2. The anti-vibration silicone sleeve 56 is a silicone part with a certain elasticity, so as to effectively eliminate the vibration of the amplitude rod 53 and the vibration of the working tip 2, which would affect the normal use of oral care.

[0074] like Figure 9 and Figure 10 As shown, the oral care device 100 is provided with a water spray channel 7. The water spray channel 7 passes through the ultrasonic transducer 51 and the amplitude transformer 53 in sequence along the extension direction of the ultrasonic transducer 51 and the amplitude transformer 53, so as to realize the function of the oral care device 100 spraying water by connecting an external water pump to the oral care device 100.

[0075] The working tip 2 has a first water outlet 71 connected to the water spray channel 7 at the end furthest from the amplitude transformer 53, which facilitates forward cleaning of the working area and makes the camera mechanism 62 capture the working area more clearly. The working tip 2 has a second water outlet 72 connected to the water spray channel 7 on its circumferential wall, which is used to clean the area around the working area of ​​the working tip 2.

[0076] The oral care device 100 also includes a base 8 for storing and charging the oral care device 100;

[0077] like Figure 1 , Figure 2 and Figure 8As shown, the base 8 includes a storage component 81, an annular shell 82 rotatably connected to the storage component 81 and having a accommodating chamber 821 in the middle, and a base shell 83 rotatably connected to the storage component 81 and disposed opposite to the annular shell 82. The storage component 81 is an annular piece and is coaxially disposed with the annular shell 82, so that the oral care device 100 can be directly inserted into the base shell 83 through the accommodating chamber 821 and the storage component 81. Multiple storage holes 811 are provided on the side of the storage component 81 facing the annular shell 82 for inserting and fixing the working tip 2. The multiple storage holes 811 are arranged at intervals around the center of the storage component 81 to accommodate the working tip 2 suitable for different working conditions, thereby improving the applicability of the oral care device 100.

[0078] The base 8 has a support component 84 fixed to it. The support component 84 includes a support column 841 and an annular support member 842 coaxially arranged with the support column 841 and connected to the end of the support column 841 away from the base housing 83. A main board module 85 is sleeved on the support column 841, and a plurality of spaced disinfection lamps 851 are arranged on the side of the main board module 85 facing the annular housing 82. The disinfection lamps 851 are arranged in annular space. The support component 84 has a notch 86 at the part corresponding to each of the disinfection lamps 851 to expose the disinfection lamps 851 for disinfecting the oral care device 100 inserted into the housing. The notch 86 is located at the transition connection between the support column 841 and the annular support member 842 so that each disinfection lamp 851 mounted on the main board module 85 can pass through and irradiate the oral care device 100.

[0079] A heating diaphragm 87 electrically connected to the motherboard module 85 is provided on the side of the annular support member 842 facing away from the motherboard module 85. The heating diaphragm 87 is also annular to facilitate heating and drying of the oral care device 100 inserted into the base 8. In addition, a receiving cavity 88 is recessed on the support member 84. The circular opening of the receiving cavity 88 is provided on the annular support member 842 and is coaxially arranged with the annular support member 842. A charging component 89 is provided on the bottom wall of the receiving cavity 88.

[0080] The charging assembly 89 includes a base 8 battery 33 (not shown) electrically connected to the motherboard module 85, an electrical contact 891 for electrical connection to the oral care device 100, and a charging terminal 892 electrically connected to the motherboard module 85. The electrical contact 891 is electrically connected to the motherboard module 85 and is exposed within the receiving cavity 88 of the support column 841. A charging support 893 adapted to the working head 14 of the oral care device 100 is protruding from the bottom wall of the receiving cavity 88. The electrical contact 891 passes through the charging support 893 and is electrically connected to the contact terminal 613 of the oral care device 100 abutting against the charging support 893. This allows the oral care device 100 inserted into the base 8 to be electrically connected to the electrical contact 891, thereby enabling the oral care device 100 to maintain power at all times for use and improving the user experience.

[0081] The control system of the base 8 provided in this embodiment of the invention is as follows:

[0082] The preset disinfection time for the disinfection lamp 851 is a;

[0083] The preset heating and drying time for the heating mold is b;

[0084] When the sensing module (not shown in the figure) integrated on the motherboard module 85 senses that the personal cleaning device is connected to the charging component 89, the motherboard module 85 activates the disinfection lamp 851.

[0085] When the disinfection time of the disinfection lamp 851 reaches the preset time value a, the main board module 85 stops the disinfection lamp 851 and starts the heating module.

[0086] When the heating and drying time of the heating mold reaches the preset time value b, the main board module 85 stops heating the mold;

[0087] When the battery 33 (not shown in the figure) is fully charged, the motherboard module 85 stops charging and shuts down all circuits of the smart base 8.

[0089] The main control module 3 is equipped with an image imaging processing module for converting the images captured by the camera into image signals and sending the image signals to the display terminal;

[0090] in,

[0091] The first image signal acquired by the camera is a scan of the current user's facial information;

[0092] The image processing module includes a comparison module;

[0093] The comparison module compares the facial information collected by the camera with the facial information in the database, generates a dental model information that matches the current user's facial information, and sends the dental model information that matches the current user's facial information to the image imaging processing module.

[0094] The image processing module sends the teeth model matched with the current user's facial information to the display terminal and images it.

[0095] The second image signal captured by the camera is the current user's dental information;

[0096] The image processing module also includes a marking module;

[0097] The comparison module compares the dental model information collected by the camera with the dental model information that matches the current user's facial information, and generates a comparison signal to send to the marking module.
